Surface Tension : Part 02
Parts 00 and 01 traced rubber from the natural world through vulcanization and into the first outsoles built for the outdoors. Part 02 picks up in the late 1970s with the emergence of sticky rubber. It follows the arc from Boreal’s Firé shoe and the early Yosemite bouldering scene to the evolution of climbing rubber at Five Ten, Scarpa, and La Sportiva and the models that we see on the wall today. Along the way, it looks at the physics behind climbing rubber and how shoe structure evolved to control softer compounds. Modern climbing footwear, as a result, behaves less like a shoe and more like a glove for the foot, giving climbers precise control.
Surface Tension : Part 01
Surface Tension is a series about rubber technology in climbing, tracing traction from nature’s first templates to the chemical age. Part 1 begins when rubber entered the story and rewired what footwear could do. Climbers soon discovered that sensitivity underfoot was its own kind of safety, and the sport began demanding friction as a feature. This chapter starts at the hinge point, when tragedy met necessity and new materials reshaped how people moved through the mountains.
